The impact of climate change mitigation on water demand for energy and food: An integrated analysis based on the Shared Socioeconomic Pathways

•We use an integrated modelling framework of the water-energy-land-climate systems.•We assess the effects of socioeconomics, mitigation & water policy on water demand.•The impacts of climate change mitigation on water demand are highly uncertain.•The choice of cooling systems is a major determinant of electricity water demand.•Dedicated policies on irrigation of bioenergy and electricity water use are needed.
